CAR-BODY-UNDERFRAE CONSTRUCTION.

Patented July 3o, `1907.

Application filed January 29, 1907. Serial No. 354,6'777.

To all whom it may concern:

Beit known that I, OSWALD S. PULLIAM, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Im- 5 provcments in Car-Body-Underframe Construction, of

, which the following is a specification.

This invention relates to car-body underframe construction and particularly to the form shown in U. S. Letters Patent No. 833,086 of October 9, 1906.

l The object of the present invention is to provide a i l after described and claimed.

In the accompanying drawing which illustrates an application of my invention, Figure 1, is a part elevational and a part sectional View of a construction embodying my invention; Fig. 2 a side elevational view of a transom or body-bolster shown by Fig. 1 with the center-casting, lfiller-blocks Aand-cent'er-sills omitted; Fig. 3, a perspective view of center-casting; and Fig. 4, a detail view showing a filler-block in a center-sill.

Referring to the drawings, 'I have shown a transom in the form of a body-bolster, but my invention may be employed for an intermediate transom as well as a body- ,bolstexz As illustrated and as preferred, the transom y or body-bolster comprises a top-member 1, abottommember 2, and avvcrtical web 3 joining;y the top and bottom-members. The bottom-member 2 is cutaway at its center and the web is formed lwith'vertically extending separated recesses, 4 located a slight distance from the center of the transom. Forming the recesses as shown leaves a central web-portion 5 which latter constitutes an integral cmnpression-member. The recesses 4 are designed to receive the-draftmembers or center-sills 6. The center-sills are preferably of channel-form. Each recess 4 is located between the central web-portion 5 and Ranges 7, which latter extend out- Harige 13. Located in'therecesse's and set into the center-sills, are two independent filler-blocks 14 one for each recess. These filler-blocks are secured in position by b'o1ts 15 which pass through flanges 7, upright-inembers 10 and the center-sills. When the parts are assembled, flanges 16 fit into the spaces formed between the upright-members 10 and the flanges 13 ot' the centercasting and are connected to said casting by bolts 17.

The upper andlowercnds of the independent fillerblocks are slightly inclined as shown for the purpose of enabling the blocks to t snugly in the center-sills. These independent and removable filler-blocks are particularly designed i'or use in connection with the other 60 parts described, in Ycases where the channel center-sills are rigidly joined together by a plate entending across the tops ot' the sills and extending either the entireI length of the sills or for a portion oi their lengths. In vsuch cases it is impossible to spring thecenter-sills inl Wardly sufficiently to remove the center-casting having the filler-blocks made integral therewithe lblocks interposed between the upright-members and centersills, said center-sills, upright-members and filler-blocks 1ocated in the recesses, and means for connecting the centersills, upriglit-memlwrs filler-blocks and transom. Y

3. In n car-body underframe, the combination with channel-shaped center-sillsy of a transomvformed with separated recesses to receive the center-sills. a removable center-casting provided with two disunited upright-members, independent ller-blocks tted into theI center-sills and located between a center-sill and an vupright-memlmr of the ccnter-casting. said center-sills. and upright members located 9() in the recesses. and means for connectil'ig,r the center-sills, upright-members. filler-blocks and transom. In testimony whereof I alix my signature in presence of two witnesses.
